WILHELM VOGEll, OF FREIBURG, BADEN, GERMANY, ASSIGNOR TO THE FIRM OF S.DUKAS, OF SAME PLACE.

AUTOMATIC ELECTRIC GAS-LIGHTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 239,896, dated April 5,1881.

Application filed November 16, 1880. (No model.)

To all whom it may concern Be it known that I, WILHELMVOGEL, a subjectof the Emperor of Germany, and a resident of Freiburg, Baden, Germany,have invented certain new and useful Improvements in AutomaticGas-Lighting Apparatus, of which the following is a specification.

The object of my invention is to construct a simple and economicalapparatus for automatically turning on the supply of gas to any numberof burners and simultaneously lighting the gas-jets by electricity. Thisobject I attain in the manner which 1 will now proceed to describe,reference being had to the accompanying drawings, in which- Figure 1 isa front view of my improved gaslighting apparatus with the outsidecasing in section; Fig. 2, a corresponding side view, and Fig. 3 avertical section.

A is the gas-tube, bent as shown in Fig. 3, provided at its upper on dwith the usual burner B, and threaded at its lower end for attachment toa suitable gas-bracket or chandelier. This tube is provided with afour-way cock, 7r, the stem of which carries on the outside aratchet-wheel, r, Fig. 2, having eight teeth.

Secured to a projection on the tube A is an -clectro-magnet, E,insulated from the tube,

and resting on one edge of the poles is an armature, g, which, when theelectric circuit is not closed, is kept raised by means of a spring, It,as shown in Fig. 2.

To the outer end ot'the armature,at one side, is pivoted a pawl, t',which engages with the teeth of the wheel r under the action of aspring, l. To the outer end of the armature, g, on the other side, ispivoted a rod, n, connected to an arm on a cock, l, adapted to a conicalseat in an enlarged part of the tube A, above the cock k, the cock lbeing held to its seat by a spring, 19. This cock is provided with anopening communicating with the interiorof the tube A, and also with anoutlet, 1n, within a short distance of the burner. About this outlet mis arranged a piece of platinum wire, a, communicating through the wireI), coils c d e of the electro-magnet, and wire f with a suitablebattery capable of making the platinum wire red hot, the circuit beingcompleted through the gas-tube A and pipes.

The devices are preferably inclosed in a removable casing, VI.

Supposing the cook to be in such a position as to cut oft the supply ofgas from the burner and it is desired to light the gas, the electriccircuit is then closed. This will have the effect of attracting thearmature g, drawing with it the pawl i, which will thus turn the cock kan eighth of a revolution and open the communication to the burner. Atthe same time the cock l is so turned, through the medium of the arm n,as to open the communication with outlet m, so that the gas, escapingthrough this opening and coming into contact with the platinum wire a,which has been made red hot by the electrical current, ignites, and theflame thus formed, passingoutthrough an opening in the casing, ignitesthe gas at the burner B. The circuit being then broken, the armaturereleased is raised by the spring, the cock lclosed, and the pawl 6 movesto the next tooth, so that by closing the circuit again the cock It willbe turned so as to cut 011' the gas supply and so extinguish the light.By this means any number of gas'burncrs may be lighted from a centralstation.

I claim as my invention-- 1. The combination of the gas-burner,electro-magnet, armature, and electric circuit with a rotary cock, I,having an arm and a rod, a, connecting it with the armature, an outlet,m, adjacent to the burner, and a platinum wire in the circuit oppositesaid outlet, as set forth.

2. The combination of the gas-burner, electro-magnet, armature, andelectric circuit with cock 7t, its ratchet-wheel and spring-pawlconnected to the armature, and the cock 1, adapted to be operated bysaid armature, and having an outlet, m, adjacent to the burner, and aplatinum wire in the electric circuit opposite said opening, allsubstantially as described.

In testimony whereofl have signed my name to this specification in thepresence of two subscribing witnesses.

WILHELM VOGEL.
